    Aside from the improved screen, can anyone give me an idea of how much of a performance difference I might see from going from a 2013 to a 2014 iMac with the specs listed below. The Mac will be used for Premiere, After Effects, Photoshop, Lightroom, etc.

    2013
    3.5GHz i7
    32GB 1600MHz DDR3
    512GB Flash Storage
    NVIDA GeForce GTX 780M 4096 MB

    to a

    2014 model
    4.0GHz QC i7 Turboboost 4.4GHz
    32GB 1600MHz DDR3 SDRAM-4x8GB
    512GB Flash Storage
    AMD Radeon R9 M295X 4GB GDDR5

    Thanks!

    How much better would you say the Gtx 780 is over the AMD Radeon R9 M295X? Significantly or minimally?

    Why would the iMac from a year prior have a better graphics card? I believe both the 2013 and 2014 options listed were the highest end available at the time.

    It doesn't.

    Unless you're made of money I would at least wait until the next update because you might see TB3 and other interesting enhancements (maybe even eGPU support?). You rarely see a massive performance boost from just one generation to the next.

    The guy's wrong.

    For what you're doing, the M295X will be leaps and bounds better, because what you're doing is heavily OpenCL, and NVIDIA cards (especially the Kepler 600M/700M series) suck at OpenCL. AMD cards are bloody good on OpenCL.

    I got the exact same retina iMac (4.0 i7/32/512/4GB M295X) and it does a great job at 4K editing.
